Title: Improvements in or relating to integrated circuits
Inventor: WILSON BRYAN LORRAIN HUMPHREYS
IPC: H01L27/00
Filed: 1968-02-21
Abstract: 1,216,004. Electroluminescence. PLESSEY CO. Ltd. 7 Feb., 1969 [21 Feb., 1968], No. 8446/68 Heading C4S. [Also in Division H1] An integrated circuit electroluminescent display comprises a semi-conductor substrate, a plurality of EL elements formed on same, semiconductor means, e.g. two series connected junction or metal-oxide-silicon-field effect-transistors Q 1 , Q 2  or bi-stable stages associated with each EL element for selective application of an activation signal, and storage means including a transistor, e.g. metal-oxide silicon field effect transistor Q 3 , associated with each of the elements for causing its associated EL element to luminesce for a period substantially longer than the period of the activation signal. The semiconductor and storage means are formed on the substrate and arranged such that each EL element and its associated semi-conductor and storage means form individual groups on the substrate. The substrate may be single crystal and the EL element a junction photo-diode. Activating signal S (Fig. 2, not shown) may have superimposed synchronizing pulses (4) and (5) for activating line and frame scanning circuitry (2) and (3) respectively. Activation of Q 1 , Q 2  cause the application of the analogue signal to Q 3  connected between D.C. potential V and reference source E, normally earthed and connected to the substrate. Storage time depends on the self capacitance C of Q 3  and and additional external capacitors. Devices Q 1 , Q 2  and Q 3  are located near the EL element so that stray capacitance effects are minimized. Desirably, the EL element and Si substrate have an epitaxial relationship, e.g. as with a P-N diode; GaP, SiC, ZnS and CdS on Si are instanced, and also polycrystalline or fibre oriented layers in ZnS or ZnSe. Suitable junction diodes may also be an emitter of ZnSe on a Ge substrate and GaP on substrates of GaAs, GaP, sapphire and Si. Solid solution emitters of GaAs-GaP, InP-GaP, AlAs- GaAs, A1P-GaP and heterojunction emitters, e.g. p = (Ga, B) P; n = Gd (S, Se) are mentioned. The use of a sapphire substrate would require circuitry in a single crystal material deposited on a Si substrate for instance. Other types of localized non-linearity may replace the above switching devices, e.g. a PN-PN diode, and linear arrays are mentioned. Uniformity of emission of the array may be increased by covering with a photographic emulsion which selectively darkens, preferably without further development, according to the brightness of each element.
